Problems solved by technology

[0004] In turn, this may unlock the telescoping tube, and the user may have to manually extend or retract the telescoping tube to obtain the desired handle length
Furthermore, the user may have to operate the button again to lock the locking bolt in order to secure the telescoping tubes relative to each other
This can lead to an inefficient and uncomfortable way of changing the length of the handle
In addition, the buttons may be located far away on the handle, which may make their operation difficult and inconvenient

Abstract

An extendable tool (100) includes: an outer tube (102); an inner tube (108) including at least one receiving portion (206, 214); and a handle portion (112) including a slot (114) disposed therein. A sliding member (116) is disposed within the slot (114) and adapted to slide within the slot (114) between a first position (P1) and a second position (P2). The extendable tool (100) also includes a locking element (208) adapted to selectively engage the at least one receiving portion (206, 214) such that the locking element (208) constrains the inner tube (108) relative to the outer tube (102 )exercise. The extendable tool (100) further includes an engagement member (210) having an inclined surface (212) coupled with the slide member (116). The engagement member (210) is adapted to slide within the outer tube (102). In the first position (P1), the sliding member (116) actuates the engaging member (210), whereby the inclined surface (212) of the engaging member (210) engages the locking element (208) with the at least one receiving portion (206, 214 ) engagement.

Description

technical field [0001] The present disclosure relates to an extendable tool, and more particularly, to operational aspects of the extendable tool. Background technique [0002] Typically, hand-held machine tools, such as pruning tools, may include a pruning head coupled to a handle. The handle can be used to hold the pruning tool during pruning operations. In many cases, pruning tools can be used in inaccessible or hard-to-reach places, such as deep in bushes, raised places above the ground, etc. In this case, it may be difficult to complete the pruning operation with the required precision and quality. [0003] Thus, in some applications, the handle of the pruning tool may have an extension feature, such as a telescopic extension. The handle may include interconnected telescoping tubes that may be extended or retracted as appropriate to increase or decrease the overall length of the pruning tool's handle, respectively. Telescoping extension of the handle may be provided...
